Terminology
Pulse
It’s a single disturbance in a medium.
Transverse
Pulse
It is a pulse in which the particles of the medium move at right
angles to the direction of motion of the pulse.
Amplitude
It is the maximum disturbance of a particle from its rest
(equilibrium) position.
Principle of
Superposition
It is the algebraic sum of the amplitudes of two pulses that
occupy the same space at the same time.
Constructive
Interference
The phenomenon where the crest of one pulse overlaps with the
crest
of another to produce a pulse of increased amplitude.
Destructive
Interference
The phenomenon where the crest of one pulse overlaps with the
trough of another, resulting in a pulse of reduced amplitude.
Transverse
Wave
A wave in which the particles of the medium vibrate at right
angles to the direction of motion of the wave. A transverse wave
is a succession of transverse pulses.
Wavelength
The distance between two successive points in phase.
Frequency
The number of wave pulses per second.
Period
The time taken for one complete wave pulse.

3 Revision: Grade 10 Term 1 2023
Amplitude
The maximum displacement of a particle from its equilibrium
position.
Crest
Highest point (peak) on a wave.
Trough
Lowest point on a wave.
Wave Speed
The distance travelled by a point on a wave per unit time.
Longitudinal
Wave
A wave in which the particles of the medium vibrate parallel to the
direction of motion of the wave.
